This application is a continuation in part of my application Serial No. 627,458, filed August '4, 1932. I

This invention relates to record retaining devices and more particularly to the type in which a plurality of such devices are provided for selection at will.

The main object is to provide an arrangement whereby a great number of record retaining devices may provide the devices of suitable material so that records may be represented thereon by means of electro-magnetic effects.

The conventional arrangement for retaining records which may be obtained at will consists usually of a group of wheels which are rotated to set up a value and then rotated again to represent .the value determined by the set-up. Such arrangements require the provision of a large number of wheels occupying considerable space and the employment of suitable operating devices therefor necessitating moving large masses and the objectionable mechanical dii'liculties increase as the number of groups are increased.

Distinguishing therefrom the present invention utilizes strips or other elements of steel or other magnetizable material each of which records by point by point magnetic effects, and such magnetic effects of all strips are transcribed to represent upon a series of wheels the data previously entered upon the strips. As other and subsequent data are sometimes required provision is made for neutralizing the magnetic effects upon the strips so that other and new data may be represented by the same strips.

The transcription does not necessarily depend upon a series of point magnetizations as diflferently located points may be magnetized to control differential effects. In addition, there may be superimposed over such magnetized points variations in magnetism effected by variations in electrical rmistance determined by sound, such as speech, directed into a transmitter. The various strips thus magnetized may be selected at will for reproduction of the sound effects previously stored in the strips in the form of variations in magnetic effects. The reproduction is preferably effected by the same transmitter which is employed to produce the variable magnetic effects.

The invention is applicable in conjunction with systems for determining the status of an account. Such information is derived by transcribing the magnetic effects upon a selected group of wires, strips or other elements of mag- ,change represented by new be provided in a small space and to netizable material and representing such effects upon a group of wheels. As the amount represented may be changed by a transaction, the positions of the wheels is recorded upon the selected group of strips for subsequent representation. Also, if desired, upon such strips there is registered under control of a telephonic device information relative to the account which may be reproduced at will. The latter feature may be used independently of the account representations and is to be construed as an object of the invention.

The invention is illustrated in the drawings in which Fig. 1 is a view in side elevation, partly fragmentary, of the unit containing the selectable groups of elements which record data by means of magnetic eflects.

Fig..2 is a plan view of the apparatus disclosed in Fig. 1, also partly fragmentary to show more clearly certain parts.

Fig. 3 is a plan view of the unit which is employed to select the groups of record representing elements.

Fig. 4 is an electrical diagram coordinating the two units disclosed in Figs. 1 and 2 with a data representing apparatus or unit.

Fig. 5 is a diagrammatic representation of the operating devices for one of the data representing devices. v

The record representing devices are selected by a dial mechanism comprising a dialing plate III (Fig. 3) having a series of finger receiving apertures II. The actuation of the plate III by a finger to a position determined by a finger stop piece i2 turns said plate one or more steps depending upon which aperture ii is employed for the actuation.

Plate III is attached to a stud l3 and to said stud is secured an arm I4 and a gear I5. The arm it carries a pawl l6 which has an approximately rectangular pin I'I in the plane of a ratchet wheel 18 which is attached to a dentated disk l8, and both wheel 18 and disk I! are loosely .mounted on stud IS. The gear l5 meshes with a pinion 20 to drive a suitable centrifugally controlled governor II, which forms no part of the present invention.

The dentated disk i9 as it turns one or more steps is adapted to successively close contacts 22 which are normally open.

For example, to select the record representing device 20, as dial i0 is turned three steps clockwise pawl IE will ratchet over wheel II to position the pin H to cooperate with the radial edge of one of the ratchet teeth. when turning dial ciently long so as to perform their functions in plate ll ina clockwise direction a spring 28 comany position of the rod II which might have nected to a lug 24, which is part of a circular been effected by the first dialing operation As plate II also secured to stud II, will be tenrod 40 is turned by pawl ll such actionis effected sioned so as to restore dial plate II to normal against the tension of a spring 12 one end of when the finger is taken out of the previously e a led aperture II. In so doing pawl II will drive ratchet wheel ll contracl ckwise and disk II will successively close contacts 22 three times. When 0 is dialed, contacts 22 will close once nly The record representing devices are contained in a separate controlling unit shown in Figs. 1 and 2 and comprise a baseboard II to which is secured a pair of supports 21 and is and said supports carry a vertically-movable circular tube of insulating material 29 which has a pair of integral ears 8| and the latter are provided with slots II to receive studs 82 which are carried by the supports 21 and 28 may be raised or lowered.

Axialiy aligned with the tube 2! and movable relatively thereto both lengthwise and around ten conical frusta II to provide a series of shoulders 42 adapted to be engaged by a pawl ll pivotally carried by the armature H of a magnet 45.

Referring to Fig. 4, it magnet It is wire 41 to closed contacts 48, contacts 22 to the negative line side.

If three impulses are transmitted by the dial mechanism pawl 48 will successively step rod 40 upwardly and each successive position as well as the last position willbe held by a retaining pawl II also coacting with shoulders 42.

After the desired longitudinal movement of rod ll is effected a rotary movement is then iven.

To this end, referring to Fig. 3, it will be apparent that when lug 24 is shifted by the initial manual positioning of dial plate ll, contacts 53 will close. By a wire I (Fig. 4) the circuit extends through such contacts I! from the positive line side to one side of a magnet 55, the other side being connected to the negative line side Bl.

When magnet 55 (Fig. 3) is energized it will attract its armature and shifts. pawl 86 pivoted thereto so that the latter will move into a notch 51 in a cam disk II and is held therein until contacts 53 open when the dial plate returns to normal. When contacts 53 open magnet II is deenergized to permit a spring It to shift pawl 50 to turn cam disk 58 one step. Such turning of disk ll brings a cam portion thereof into a posithe dropping of the interclose contacts 02 and open contacts 48. The shifted position of disk 58 is held by retaining pawl OI coacting with a notch 64 in said disk is.

As "0 is dialed after a previous dialing has left the contacts 62 closed, contacts 22 are closed only once and the one impulse is directed through contacts '2 (Fig. 4) by wire I to magnet and thence to the positive line side It.

The armature i! of magnet H (see Fig. 2) is pivoted at II and the armature has pivoted thereto is a spring urged holding in order that the tube which is connected (Figs. 1 and 2).

The purpose of the axial and rotary motion of rod 40 will now be explained. The upper end of god I passes through a slot 13 (Fig. 1) in table 0 so as to the periphery of disk 10 for each of the eight denominational orders, units to tens of millions. A pair of wire connections, of course, extend from each magnet so as to provide suitable wire connections to said magnets.

magnetizable material such as steel there being provided ten of such strips in a group, and eight groups corresponding in denominations.

represent any numerical digit value. Each strip or a group represents a denominational order as well as a digit value in that order.

grouped in denominations, or art, are interspersed. All

tively to the digits 0-9, and there are ten tiers to represent records 0-99, 100 records or accounts in a minimum of space.

Since record 20 was selected the third tier will be correlated with magnets ll since magnet II will receive three impulses. When 0" is dialed the rod 40 will be turned one step and thus the magnets 84 will be shifted from a neutral position so as to be correlated with the eight denominational strips 1| (that is the first strip in each group) which strips represent record "0 in tier #3. It will be understood that the dial II will be operated twice in succession, and that the first dialing will effect a selection of a particular tier by a longitudinal movement of the rod 40, while the second dialing will effect the selection of a particular element H in each of the circumferential or rotary motion of the rod II and the magnets ll carried thereby.

Assuming that the eight strips have been previously magnetized, each having the same or different number of magnetized points, and it is desired to ascertain the numerical value represented in the selected record device, the following operation is performed.

Key 19 (Figs. 3 and 4) is now depressed so as to close contacts 80.

contacts are closed the circuit extends from the negative line side 50 (Fig. 4) through contacts 80 to a magnet 83 and thence by normally closed contacts H and wire it to the positive line side 4.

From Fig. i it will be magnet II is energized it attracts its armature 86. The latter carries a stud ll of insulating material which normally holds the lower blade 8! of contacts 14 upwardly to keep such contacts closed. Therefore, when magnet 83 is energized,

the machine provides for observed that when it opens its circuit by opening of contacts ll.

Pivoted to armature 99 is a pawl 09 coacting with a ratchet wheel 99. A springfla holds pawl 99 in ratchet wheel operating position and also elevates armature 99 when magnet 99 is deenergisedby opening of contacts 14.

Thus, it will be clear that armature 99 will vibrate a number of times until the circuit to magnet 92 is permanently opened, by means to be presently explained.

To ratchet wheel there is secured a toothed wheel 900. This wheel coacts with a toothed wheel 90b, which turns twice during one revolution of the wheel 90a. To the wheels 99b and 99 there are secured cams 9I and 92 respectively, the periphery of cam 9| coacting with a lower extension of the right ear 90 of tube 29. After rod 40 has been longitudinally positioned to select a record the points of the conical ends 04A of the magnets register with the tops of strips I9 and for each step oi rotation of ratchet wheel 99, cam 9| causes the tube 29 to be raised one step so that for ten steps of rotation of ratchet wheel 90 the magnets register with ten successive points of the strips 19. Thus the conical points A analyze the strips for determination of magnetized points.

After a quarter of one revolution of cam 92 from the initial position shown in Fig. 1, a projection 99 of a disk 99 secured to cam 92 will, at the tenth position of the magnets 94, engage the upper blade of contacts 99 to close said contacts. Such contacts extend the circuit from the positive line side to one side of a magnet 99 (Fig. 4), the other side being connected to the negative line side 50. When magnet 99 is energized it attracts its armature 91 which is an integral part of the detent plate 92 and as the latter is shifted it releases depressed key I9 to open contacts 90. The circuit to magnet 03 (Fig. l) is now opened at the tenth analyzing position and operation of pawl 09 thus stops.

By magnetic induction one or more electrical impulses are created in the magnets 84 and in order to register such effects on an accounting device for visual representation the following action takes place. Hereafter, numerical sub-scripts designate denominational orders.

Considering magnet 941, it will be observed that in a closed circuit including such magnet are two sets of normally closed contacts 981 and I901 and a relay magnet 991. The magnet 991 when energized will close its related contacts I00: thereby extending a circuit from the positive line side by wire 95, thence by a wire IIII through closed contacts I001, and thence by wire I02 to one side of a magnet I091. The other side of the latter is connected by wire I04 to the negative line side 50.

Magnets I091-I09a correspond to magnets of any suitable electrically controlled number representing device and may comprise the apparatus shown in Fig. 5 of the British Patent 372,742 and also herein diagrammatically in Fig. 5.

For each electrical impulse to magnet I091 an armature H0 is attracted so that by a pawl III and gear II2 a related accumulator wheel or number wheel I I9 will be turned a definite amount to represent the numerical values represented by the number of magnetized points of the related steel strip I0.

It will be noted that in the particular construction illustrated by Fig. 5 the number wheel II3 has three zero positions, as indicated by the three notches in its periphery, and said wheel therefore has three series .0! digit numbers (from .0 to 9). The gear III and pawl III are so constructed that each feed movementof said pawl will advance the gear H2 and wheel III one step, and that ten such steps will turn the number .wheel III from one of its three zero positions to the next. In other words, each feed movement of the pawl III will impart one-thirtieth of a revolution to the number wheel H3.

when the operator has visually read from the wheels III the record on the strips I0 the wheels are reset to zero by means fully explained in the aforesaid British patent. If a new number changed by some transaction is to be represented upon wheels Ill they may be turned manually, or by a cash register, tabulator, etc., so as to represent a new record. Magnets I09 have suitable wire connections Ill for impulse actuation under control of any suitable machine so as to set wheels to represent a new amount.

It is desirable, further, to neutralize the magnetic elfects and thus permit the strips I9 to be remagnetized at points to record the new value. To enter a value to be represented by one or more magnetized points in a series of strips constituting an account device a key II9 (Fig. 3) is depressed. When the key is depressed contacts 99 and (I It will be closed and retained closed'by the detent plate 92 acting in the manner described in connection with key I9.

When contacts I I9 are closed a wire connection I25 connects the negative line side to one side each of a pair of magnets I20a and I282). The contact 90e is closed by the cam 90d (Fig. l) to one side of magnet I90, the other side of this magnet being connected by wire 05 to the positive line side. When magnet I90 is energized the armature thereof pulls a member I93 upwardly so that the pins thereon close contacts I9I1I9Ia, which are connected with the positive line side. When magnet I26a is energized the armature thereof pulls a member I2Ia downwardly so that pins thereon open contacts I901-I90a and close contacts I291--I28a thereby connecting each pair of the related magnets 99 over the contacts I9I with the positive line side.

When magnet I29b is energized a member I2lb is shifted downwardly and by pins I29 carried thereon contacts 991-988 are opened and a series of contacts I031-I03a are closed. Such contacts IMP-I03; close the left side of the series of magnets 991-945 together so that by a wire I39 one side of all magnets is connected to the negative line side 50.

When magnet 09 (Fig. 4) is energized by closing of contacts 90 upon depressing key II5, contacts I4 will be successively closed and opened thirty times as described before. of the pawl 99 will by means of the cam 9| lower and raise the tube 29, and during this movement the constantly energized magnets 04 will neutralize the magnetic effects of the related steel strips. If so desired, selecting means may be provided so as toenergize magnets 94 by a higher voltage to more effectively neutralize the mag netization.

At the end of this movement by the position of cam 900 (Fig. 1) contacts 90c open thereby connecting the magnets 04 through contacts I92 to related contacts I01. Contacts I94 close so that each time the armature of magnet 03 operates by opening and closing of contacts III, current impulses will be directed from the positive line side to a wire II9 (Fig. 4). The pawl 09 will now be operated ten steps thereby lowering the The first twenty steps tube 2! again and during this time contacts II! will under certain conditions direct ten impulses to the wire III.

Considering the control of magnet Illi, for example, it will be seen that from II! two paths are supplied, one through upper contacts llli to magnet '..l, and thence by wire Ill to the negative line side, or by lower contacts I011, thence by wire I" to contacts I021 and I201 now closed, thence to magnet 1, contacts Illl, now closed and wire III to the negative line side.

As best shown in Fig. 5 contacts III; are opened at zero position of the wheel III and contacts Ilh are closed at the zero position. If the wheel stands at "6 contacts |..l are closed and contacts I011 opened. Hence, the first four electrical impulses will be directed through contacts Illi to the magnet IlIl so as to give four feed steps to the wheel. As the wheel is now at zero contacts I001 open and contacts Il'li close. Thus the subsequent six electrical impulses will be directed to magnet 1 to result in the magnetization of the related steel strip II at six points.

During the time the six electrical impulses are being directed to magnet 1, cam II is being turned clockwise by pawl II and in this operation raising the tube 29. The conical points a of the various magnets Cl will cause point energizations in accordance with the standing of the accumulator wheels Hi. If a wheel stands at 0" each of the ten points of the related strip ll will receive a point of magnetization and in clearing to set up the representation the wheel will again be turned ten steps to represent 0".

Alter the amount has been recorded by point magnetizations contacts 95 (Fig. 1). are closed through the action oi projection 93 on the disk 84 thus energizing magnet 06 and releasing the depressed key Iii in the manner previously explained in connection with the releasing or key 19.

At the termination of the entry operation key I (Fig. 3) is depressed to close contacts Iii thus extending a circuit from the negative line side 50 through the closed contacts Iii to a magnet I52 and thence to the positive line side I (see Fig. 4). When magnet I52 is energized it will attract its armature I53 and by means of a slidably mounted member I5 (Fig. 2) integral with the armature I51 a projection I55 will be shifted and since it Fig. l) engages holding pawl II the latter will be released from one of the teeth of wheel Ill. Q

An extension I56 of pawl 69 is engaged by pawl H so as to free pawl 69 from the teeth of wheel 10. As the latter is now free of pawls 09 and II it will return to normal under action of return spring 12.

Upon the initial turning of wheel I. to select a group of record representing devices a projeciion I51 (Fig. 2) thereof passes away from a plate I58 which is bent at right angles to form a plate I59 which is pivoted at I to the base plate 26. Plate I59 therefore permits opening of contacts I H.

When the plate returns to normal, contacts Iii will close and referring to Fig. 4, closure thereof will cause magnet I! to be energized since key I5! is kept down by the operator to hold contacts I5I closed. E

Magnet It! will attract armature I (Fig. 1) to shift an integral slide I and a pin I" carried at its extreme which engages a fork in pawl ill will release the same from a shoulder ll. By suitable connections such as a pin I on pawl II engaging pawl II the latter may also be shifted. Thus rod I and attached parts drop to normal position.

Further, with respect to Fig. 3, it will be seen that depression of key I" will also took an extension CI of the holding pawl 63 to free it from notch 60. Extension I will depress a plate I" so that by means of a stud carried by a curved portion or said plate pawl II will be rocked. As plate II is now free of both pawls N and N a suitable spring I" may return it to normal.

All the operated parts are now at normal in readiness for selecting another group of strips II to analyze another record.

By means of a transmitter I'll which also functions as a reproducer the current in magnet". may be varied according to sound vibrations to record speech upon the correlated strip II. For controlling such, transmitter I'll has wire connections Ill and ill to said magnet 84.. This arrangement permits a magnetization of strip ll varying with sound vibrations to be recorded by the strip together with point by point magnetizations of the same strip. These sound vibrations are recorded magnetically, and the induced currents produced with the aid of such magnetic record aflect only the transmitter. The sound vibrations may be remarks relative to certain accounts, such as "account overdue", and are audible when the value of the account or record is transcribed.

It is understood that in accordance with the nature of the relay magnets 99 and the transmitter Ill any known amplifying means may be employed to amplify the current impulses produced in the coils N.
